      OBJECTIVES: To clarify the prevalence and severity of injuries and illnesses in university handball players. DESIGN: Prospective cohort study. SETTING: Survey-based online questionnaire. PARTICIPANTS: 231 university handball players (109 males and 122 females) over 38 weeks. MAIN OUTCOME MEASURES: Each participant completed the Japanese version of the Oslo Sports Trauma Research Center Questionnaire on Health Problems every Sunday. The main outcome measures were the average weekly prevalence of injuries and illnesses, duration, average weekly severity scores rated on a scale of 0-100 based on answers to four key questions, and cumulative severity scores. RESULTS: The average weekly prevalence was 27.4 % (95 % CI: 25.6-29.1 %) for injuries and 2.2 % (95 % CI: 1.6-2.8 %) for illnesses. Among injuries, traumatic injuries had higher average weekly severity scores (50.0 vs 32.0, p < 0.05) and cumulative severity scores per case (65.0 vs 42.0, p < 0.05) than overuse injuries. Conversely, overuse injuries lasted approximately 10 days longer than traumatic injuries (18 days vs 10 days, p < 0.05). Traumatic knee injuries and overuse shoulder injuries ranked the highest in prevalence, duration, and cumulative severity scores. CONCLUSIONS: We found that, although overuse injuries were less severe than traumatic injuries, they interfered with handball activities for extended periods.

      OBJECTIVES: This study aimed to examine injury surveillance practices in a variety of university sports teams and barriers and facilitators for injury data collection and utilisation. DESIGN: Cross-sectional study. SETTING: University sports teams in Japan. PARTICIPANTS: Medical, coaching, and other staff (non-medical/-coaching staff) of the university sports teams in Japan. MAIN OUTCOME MEASURES: The survey included 31 questions that examined the barriers and facilitators for injury data collection, and the type of data on injury and exposure collected. RESULTS: Injury data were collected during matches for 69 teams (48.3%) and training for 61 teams (42.7%). Injuries were primarily captured by athletic trainers in teams with medical staff, coaching staff and athletes in teams without medical staff. Common barriers in collecting and utilising injury data included limited funding for trained personnel and lack of time for medical staff to record data. Facilitating factors included clarification of the methods employed in recording and utilising injury data for teams with medical staff and the deployment of trained personnel to record injuries for teams without medical staff. CONCLUSIONS: Approximately half of the Japanese university teams collected injury data. Considering barriers and facilitators is crucial to facilitate the collection and utilisation of injury data.

      OBJECTIVE: Adequate conditioning results from various physical, environmental, and psychological factors in sports activities. In this study, we aimed to clarify the concurrence and relevance of injuries, psychological problems, and sleep disturbance in university football (soccer) players. Biomechanical characteristics and risk factors for those injuries were also investigated. METHODS: Overall, 1,084 university football players participated in this cross-sectional study using a web-based health history questionnaire. Assessments were made via the presence of injuries for physical problems, the Athlete Psychological Strain Questionnaire (APSQ) for psychologicalproblems, and the Athlete Sleep Screening Questionnaire (ASSQ) for sleep difficulties. RESULTS: There were 200 (19%) athletes with injuries; 413 (38%) of these were APSQ-positive, 246 (23%) were ASSQ-positive, and 468 (43%) athletes had no physical, psychological, or sleep problems. APSQ-positive respondents were significantly more likely to have a current injury than those who were APSQ-negative. No significant difference was observed between the number of ASSQ-positive and -negative respondents and current injuries. Those with sleep problems were significantly more likely to have psychological problems. CONCLUSION: More than 60% of university football players had one or more physical, psychological, or sleep problems. Players may have co-occurring problems, and it is important to address them for these athletes to reach peak performance.

      Injury prevention and health promotion among elite athletes are crucial to athletic success. Risk management requires the understanding and adjustment of physical, environmental, and psychological factors. Sleep status can be one of the essential factors for maintaining good health and preventing injury. The Athlete Sleep Screening Questionnaire (ASSQ) is expected to be an international standard for evaluating the sleep status of elite athletes. The 16 items ASSQ assess several sleep-related factors, including sleep difficulty, sleep-disordered breathing such as snoring and apnea, sleep and psychosomatic functioning during expeditions, chronotype, napping, caffeine intake, and electronic device use.

      A total of 158 male college soccer players responded the ASSQ-J and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). A factor analysis was conducted to validate the factor structure of the ASSQ-J. The internal consistency of ASSQ-J is assessed for validation. Pearson’s correlation coefficients and kappa statistic were calculated to determine if the ASSQ-J was significantly associated with PSQI-J respectively.

      Regarding the ASSQ-J-SDS, 22.4% (35 of 156) of the subjects in this study scored 8 or higher (moderate or higher), which was almost consistent with the results of a previous study on college athletes. It is clear that some Japanese male collegiate soccer players have sleep problems, as same as collegiate athletes around the world. Further research is needed for the validation of the ASSQ-J, the sleep status in a wider range of ages and sports are also investigated.

      Stability training is often carried out in the field of sports to improve performance. Appropriate loading is important in sports rehabilitation. Rehabilitation that ignores progressive characteristics can lead to a variety of reactions, including prolonged return to work and recurrence of injury. Therefore, it is desirable to objectively evaluate the load exerted by each training method. However, the degree of change in muscle activity in response to changes in foot ground contact height and stability when performing front bridge was unknown. Thirty-seven healthy subjects performed six different front bridges with varying foot height and instability. Muscle activity was measured and examined during implementation. Surface electromyography was used to measure the activity of the upper trapezius, lower trapezius, serratus anterior, rectus abdominis, external and internal abdominal oblique muscles, rectus femoris, and tibialis anterior. The rectus abdominis, external oblique abdominis, and internal oblique abdominis muscles showed significantly higher activity under conditions of instability of the foot ground contact surface. The upper trapezius, serratus anterior, external oblique abdominis, and tibialis anterior muscles showed significantly higher activity under conditions with a high foot ground contact surface. The upper trapezius, serratus anterior, external oblique abdominis, and tibialis anterior muscles required significantly higher muscle activity under high foot ground contact conditions. It was also suggested that the trunk muscles required significantly higher muscle activity under conditions where the foot ground contact surface was unstable.

      The Oslo Sports Trauma Research Center Questionnaire is an athletic epidemiological survey questionnaire targeting “all complaint injuries” (all problems with symptoms). The questionnaire includes questions regarding (1) participation, (2) modified training/competition, (3) performance, and (4) pain (symptoms) due to an injury at specific location or health problems at certain intervals. The prevalence and severity of problems are calculated to monitor changes in these parameters. This paper provides an overview of this questionnaire, its procedures, and major previous studies.

      BACKGROUND: Epidemiological data on sports injuries and illnesses depend on the surveillance methodology and the definition of the health problems. The effect of different surveillance methods on the data collection has been investigated for overuse injuries, but not for other health problems such as traumatic injuries and illnesses. PURPOSE: The purpose of this study was to investigate the new surveillance method developed by the Oslo Sports Trauma Research Center (OSTRC), which is based on any complaint definition (new method), to identify health problems compared with the traditional surveillance method, which is based on time loss definition. STUDY DESIGN: Descriptive epidemiology study. METHODS: A total of 62 Japanese athletes were prospectively followed-up for 18 weeks to assess differences in health problems identified by both new and traditional methods. Every week, the athletes completed the Japanese version of the OSTRC questionnaire (OSTRC-H2.​JP), whereas the teams' athletic trainers registered health problems with a time loss definition. The numbers of health problems identified via each surveillance method were calculated and compared with each other to assess any differences between their results. RESULTS: The average weekly response rate to the OSTRC-H2.​JP was 82.1% (95% CI, 79.8-84.3). This new method recorded 3.1 times more health problems (3.1 times more injuries and 2.8 times more illnesses) than the traditional method. The difference between both surveillance methods' counts was greater for overuse injuries (5.3 times) than for traumatic injuries (2.5 times). CONCLUSIONS: This study found that the new method captured more than three times as many health problems as the traditional method. In particular, the difference between both methods' counts was greater for overuse injuries than for traumatic injuries. LEVEL OF EVIDENCE: 2b.

      This study investigated the occurrence of physical and psychological issues among male university soccer players and examined their impact on performance. The findings revealed that over 60% of the players are dealing with either physical or psychological issues, or sleep problems, all of which significantly affect their performance. Notably, the magnitude of fatigue and changes in BMI were found to be associated with the occurrence of physical issues, and chronotype was suggested to be linked to psychological problems.

    • The effect of forefoot landing on prevention of sports injury. -Focusing on the anterior cruciate ligament injury-

      Grant amount：\4290000 （ Direct Cost: \3300000 、 Indirect Cost：\990000 ）

      In the prevention of anterior cruciate ligament (ACL) injuries, the forefoot strike (FFS) could be a safer landing technique than the rearfoot strike (RFS) during cutting motions. In this study, we aimed to clarify the joint angles, ground reaction forces (GRFs), and muscle activity levels associated with FFS and RFS landings during 180°turns. Our results showed significant differences in the lower-limb angles, muscle activities, and GRFs between the FFS and RFS. These findings suggest that increased lateral gastrocnemius (GL) and semitendinosus (ST) activities during the FFS may prevent large amounts of tension from being placed on the ACL and thereby reduce the risk of injury. Furthermore, we investigated the injury rates before and after giving out the instructions regarding the forefoot landing movement. However, no significant difference was noted between the injury rates before and after instruction.

      The aim of this study was to investigate the relationship between the muscle actibity and the risk of anterior cruciate ligament (ACL) injury.
      At 50 ms prior to ground contact, BF, ST, and GL muscle activity was significantly greater during FFS cutting than during RFS cutting, and TA muscle activity was significantly greater during RFS cutting. At 50 ms after ground contact, BF and GL muscle activity was significantly greater during FFS cutting than during RFS cutting, while TA muscle activity was significantly lower during FFS cutting than during RFS cutting.
